Taro Tanaka and Seiko’s “Grammar of Design”

“Inspired in part by the art of gem cutting, Tanaka delved into the philosophy of watch design. By 1962, he developed a series of rules for just that; he called it the ‘Grammar of Design’.

The ‘Grammar of Design’ boiled down to four basic tenets. First, all surfaces and angles from the case, dial, hands, and indices had to be flat and geometrically perfect to best reflect light. Second, bezels were to be simple two-dimensional faceted curves. Third, no visual distortion was to be tolerated from any angle, and all cases and dials should be mirror-finished. Finally, all cases must be unique, with no more generic round case designs.”
